OIL PUMP.

App1ication fi1ed April 1,

T 0 all whom it may concern:

Be it known that we, JOHN PENROD and ROBERT D. THOMPSON, citizens of the United States, residing at Okmulgee, in the county of Okmulgee, State of Oklahoma, have invented a new and useful Oil Pump, of which the following is a specification.

This invention relates to pumps and more particularly to pumps especially designed for use in connection with oil wells, it being the primary object of the invention to provide a novel form of pump. having means to trap the sand and prevent its contact with the plunger and cups of the pump.

A further object of the'invention is the provision of novel valves and valve seat arrangements, whereby the sand ladened oil may be forced upwardly to a point where the same may be discharged above the sand trap.

A still further object of the invention is to provide a pump casing of this character which may be readily disassembled to facilitate the cleaning and removing of the sand and other foreign matter therefrom.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings V Figure 1 illustrates a side elevational view of a pump tubing constructed in accordance with the present invention.

Figure 2 illustrates a vertical sectional view through the pump tubing.

Figure 3 illustrates a sectional view taken on line 3-3 of Figure 2.

Figure 4 illustrates a sectional view taken on line 4 4 of Figure 2. v

Figure 5 illustrates a sectional view taken on line 5--5 of Figure 2.

Figure 6 illustrates a sectional view taken on line 6-6 of Figure 2.

Referring to the drawings in detail, the reference character 5 indicates the outer casing of the device, there being provided in-' ternal threads 6, formed at the opposite ends 1921. 'Selfial No. 457,736.

casing being designed to accommodate the coupling 7, which couples the nozzle 8 to the caslng 5, the connection between the couplings 7 and nozzle '8 being made by the cooperating threads 9.

At the upper end of the outer casing 5 is disposed a coupling or bushing 10 which provides means for coupling the tubing 11 to the outer casing, the tubing 11 providing the means for directing the fi'uid to the discharge end of the well.

The coupling 7 is also provided with a threaded opening 12, which accommodates the lower threaded end of the working barrel 13, the upper end ofthe working barrel terminatlng at a point in spaced relation with the coupling 10 so that the fluid will have access to the sand trap '14, provided between the outer casing 5 and working barrel 13, so that particles of sand contained in the fluid may fall into the sand trap.

Supported at the upper end of the working barrel 13 is a collar 15, which has a tapered upper portion 16 to direct the plunger to the barrel 13 when the same is being dropped into the well. A plurality of openings 18 are formed in the collar 15, the openings being arranged in circular rows. From the foregoing it will be seen that as the fluid passes into the upper portion of tubing 11, the sand will fall by gravity onto the collar 15, where the particles of sand are directed through the openings and deposited in the sand trap 14. Due to this construction, it is obvious that as the plunger 17 moves by the collar 15, sand adhering to the plunger will be scraped therefrom and deposited in the sand trap.

Positioned within the lower end of the working barrel 13, is a standing valve 19, which is of the ball type and operates in the cage 20, the construction of the valve being such as to be unseated on the suction stroke of the plunger barrel and to be seated on the reverse movement thereof.

This plunger 17 is in the form of a tube and is provided with suitable cups 21 at one end thereof for providing a close fit between the lower end of the plunger barrel and wall of the working barrel to insure the suction being created within the working barrel to force the fluid upwardly therethrough. As shown, the plunger barrel is provided with an enlarged portion 22 providing a valve housing for the ball valve 23, which ball valve is restricted in its upward movement by means of the transversely extending pin 24, and restricted in its downward movement by means of the valve seat 25. 7 Thus it will be seen that on the upstroke of the plunger barrel, the quantity of fluid within a plunger .tube is held therein, by means of the ball valve 23 but on the downward movement of the plunger barrel fluid enters,

- 27 thereto, the ball valve 28, which operates b the tubular plunger and passes upwardly therethrough, the same being discharged into the tubing l1 The valve cage 26- has connection with the upper end of the plunger barrell7, and pro-' vides means for'connecting the plunger rod in the cage 26 actin to control the passage of fluid from the p ungerbarrel when the device is in operation.

When the device is in operation, it is obvious that as fluid passes from the plunger e sand or other foreign 17, to the tube 11, t

matter will fall by gravity to the collar 15,

where .the same is directed to the sand trap 14 through the openings 18 formed therein thereby preventing the sand from collecting at the point of contact between the plunger and working barrel, eliminating wear on the valve members to increase the life thereof and render the pump more efiici'en-t.

-What is claimed as new is 1; In a pump, an outer casing, a working barrel within the outer casing, a plunger operating within the working barrel, a collar disposed at the upper end of the working barrel and having an inclined upper surface, said collar having angular openings, said collar adapted to direct settling sand to a point between the outer casing and working barrel, for preventing sand from collecting around the plunger.
